At the process of ct crack and rapture evolution, the acoustic emission can not precisely reflect the meso-mechanism of rock deformation and rapture because of localization of damage.

在CT尺度裂纹演化和破坏阶段，由于岩石损伤高度局部化，声发射率参数不能精确反映岩石破坏的细观机制。

It exhibits the viscous effect under dynamic loading case, and the effect strengthens with the growth of the micro-crack density induced by the meso-damage of material.

饱和混凝土中孔隙自由水的存在对材料的力学性能有显著的影响，动态工况中主要表现为自由水的粘性效应，且该效应随细观损伤引起的微裂纹密度的改变而变化。

The relation between stress-strain and density variation of rock crack has been obtained through the meso-damage theory and damage statistics model.
